RESUMO
The efficacy of health actions, related to arterial hypertension and used as a strategy to decrease morbimortality due to cardiovascular diseases, in accordance with the "risk approach" and carried out in a Primary Health Care Clinic is assessed. These actions are based on the detection of arterial hypertension in the adult population attended at the Clinic and on the control of blood pressure levels in hypertensive individuals in which other known risk factors continue to be controlled, as well as on further treatment of eventual complications. Data relating to the 3,793 patients who were attended at least once by doctors of the adult sector of a training health-center located in S. Paulo county (Brazil) during the period from June 1990 to May 1991, inclusive, were evaluated. This evaluation was made according to each diagnosis undertaken as well as to the concentration of each type of consultation whether occasional, or follow-up. Of these 3,793 patients analysed, 839 presented arterial hypertension and/or diabetes, and were grouped into four categories: the exclusively hypertensive, the hypertensive with other associated chronic diseases (except diabetes), the diabetic and the diabetic with arterial hypertension. The results of this study brought the following aspects to light: 1) The low coverage of hypertensive individuals and diabetics being attended by the health service when only the population attended by the health service is taken into consideration. 2) The incidence of patients diagnosed as hypertensive in occasional consultations who did not return to the health service for medical follow-up indicates the difficulties involved in attracting such individuals permanently.(ABSTRACT TRUNCATED AT 250 WORDS)
